I had an experiment of boiling point in different amount of salt 
dissolved in water. The result was:
3g salt water - 100 C
5g salt water - 102 C
7g salt water - 107 C
9g salt water - 105 C
11g salt water - 102 C

After the 9g salt dissolved in water, the boiling point was lowered.
Do you know the reason why? (the salt was definitely all dissolved.)
I appreciate you if you answer my question...
